How to let a fixed "sticky" div stay outside the viewport


I'm trying to follow this tutorial: http://jqueryfordesigners.com/fixed-floating-elements/.

The problem is that whenever the fixed positioning is applied to the div, if the browser width gets changed the div moves horizontally to fit inside the viewport. In the tutorial example http://static.jqueryfordesigners.com/demo/fixedfloat.html this does not happen.

This is my code (everything is inside a relative-positioned #wrapper):

CSS:

        #cart {
            position: absolute;
            right: 0;
            width: 270px;
        }

        #target {
            width: 270px;
            height: 200px;

            background-color: blue;
            background-position: 50% 50%;
            background-repeat: no-repeat;

            position: absolute;
            top: 250px;
            right: 0;

            padding: 0;
            border-radius: 15px 15px 0 0 ;
        }

        #drag-here {
            width: 270px;
            height: 0;

            background-image: url(drag-here.png);
            background-repeat: no-repeat;
            display: none;

            position: absolute;
            top: 470px;
            right: 0;
        }

        #cart-list {
            display: none;
            position: absolute;
            top: 430px;
            right: 0;

            list-style-type: none;
        }

        .sticky #target {position: fixed; top: 5px;}
        .sticky #drag-here {position: fixed; top: 225px;}
        .sticky #cart-list {position: fixed; top: 185px;}

HTML:

<section id="cart">
    <div id="target" class="target-listen"></div>
    <div id="drag-here"></div>
    <ul id="cart-list">
    </ul>
</section>

JQuery:

sticky = false;
initialOffset = $("#target").offset().top - 5;
$(window).scroll(function () {
    if ($(this).scrollTop() >= initialOffset) {
        if (!sticky) {
            $("#cart").addClass("sticky");
            sticky = true;
        } 
    }
    else {
        if (sticky) {
            $("#cart").removeClass("sticky");
            sticky = false;
        }
    }
});

Solution

  • I think removing right : 0; in #target should do.
